Have you been tracking for some time? and if so, are you using a case insensitive file system (such as Mac, Windows)? We've noticed oddities like that before when we've renamed files to switch case.

Currently, master only shows a Zend/File/Transfer/Adapter/Http.php file, which leads me to believe this is the case for you. As such, I recommend either doing a new clone, or switching to a case sensitive drive partition.

Please note this issue is related to a Unit Test, rather than the library part of the framework.
The exact path both of the files are in are in the "/tests/Zend/File/Transfer/Adapter/" folder.
